lost
Cause
Problem with internal temperature
measurement of the drive.
The way the control unit is powered
does not correspond to parameter
setting.
Communication errors detected
between the drive control unit and the
power unit.
Connection between the drive control
unit and the power unit is lost.
What to do
"Y" indicates the auxiliary code
category.
The auxiliary code categories are as
follows:
1 = PU and CU ratings not the same.
Rating ID has changed.
2 = Parallel connection rating ID has
changed.
3 = PU types not the same in all power
units.
4 = Parallel connection rating ID is
active in a single power unit setup.
5 = It is not possible to implement the
selected rating with the current PUs.
6 = PU rating ID is 0.
7 = Reading PU rating ID or PU type
failed on PU connection.
8 = PU not supported (illegal rating
ID).
9 = Incompatible module current
rating (unit contains a module with
too low a current rating).
A - Selected parallel rating ID not
found from database.
With parallel connection faults (BCU
control unit), the format of the
auxiliary code is 0X0Y.
See A5EA Measurement circuit
temperature (page 675).
Check setting of 95.4 Control board
supply.
Check the connection between the
control unit and the power unit.
Check the auxiliary code (format XXXY
YYZZ). With parallel-connected
modules, "Y YY" specifies the affected
BCU control unit channel (0:
broadcast). "ZZ" specifies the error
source (1: Transmitter side [link error],
2: Transmitter side [no
communication], 3: Receiver side [link
error], 4: Receiver side [no
communication], 5: Transmitter FIFO
error [see "XXX"], 6: Module [xINT
board] not found, 7: BAMU board not
found).
"XXX" specifies the transmitter FIFO
error code (1: Internal error [invalid call
parameter], 2: Internal error
[configuration not supported], 3:
Transmission buffer full).
Check the connection between the
control unit and the power unit.
